Description

The present invention relates to a judgment system and judgment method that can suppress resale.

Products such as concert tickets are sometimes resold to others by the purchaser at an unfairly inflated price. In order to prevent resale, the biometric information of the purchaser of the product may be compared with the biometric information of the holder of the product to determine whether the holder and purchaser are the same person. In this case, for example, if the holder of a concert ticket is not determined to be the same person as the purchaser, the holder's entry will be restricted.

For example, Patent Document 1 discloses that a user transmits a ticket purchase request from a terminal device to a cloud server. After receiving the ticket purchase request from the terminal device, the cloud server transmits a voice registration request signal to the terminal device. In response to receiving the voice registration request signal, the terminal device accepts a voice from the user and transmits voice information including a voiceprint acquired from the voice to the cloud server. Then, by comparing the voiceprint stored in the cloud server with a voiceprint acquired from the ticket holder at the venue before entry, it is determined whether the holder is the same person as the user who purchased the ticket.

First Embodiment
A determination system 1 according to a first embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a block diagram showing an example of the configuration of the determination system 1. Fig. 2 is a flowchart showing an example of the operation of the determination system 1.

The following describes the configuration of the judgment system 1. As shown in FIG. 1, the judgment system 1 includes a communication terminal 10, a call center 20, a server 30, and a venue device 40.

The communication terminal 10 is a communication terminal capable of voice input/output and data communication. The communication terminal 10 is used by a user. The communication terminal 10 is, for example, a mobile phone or a smartphone. The communication terminal 10 is connected to the call center 20 and the server 30 so as to be able to communicate with them.

The call center 20 is equipped with a communication terminal 21 and a recording means 22.

The communication terminal 21 is a communication terminal capable of voice input/output and data communication. The communication terminal 21 is a mobile phone, a smartphone, or a landline phone. The communication terminal 21 is used by an operator of the call center 20. The operator accepts a request to purchase a product from a user of the communication terminal 10 via a voice call between the communication terminal 21 and the communication terminal 10. In the description of this embodiment, the product is an event ticket, but the product is not limited to a ticket.

The recording means 22 records a first sound from a user of the communication terminal 10 during a voice call between the communication terminal 10 and the communication terminal 21. For example, the recording means 22 acquires, as the first sound, the user's voice contained in a packet that the communication terminal 21 receives from the communication terminal 10 during the voice call. Also, for example, the recording means 22 may acquire, as the first sound, a reverberation from the user in response to the voice from the communication terminal 21.

When the ticket purchase process is completed, the communication means 23 transmits to the server 30 the first sound from the user recorded by the recording means 22, the line information of the communication terminal 10 (e.g., a telephone number), and the ticket identification information. The line information of the communication terminal 10 is acquired, for example, by referring to the communication history recorded in the communication terminal 21. The ticket identification information is assumed to be predetermined. The ticket identification information is, for example, an ID (Identification) number unique to each ticket. The ticket identification information is generated, for example, from the date and time when the ticket purchase process is completed. Here, the user refers to the purchaser of the product.

The server 30 comprises an acquisition means 31, a generation means 32, a matching means 33, a judgment means 34 and an instruction means 35.

The acquisition means 31 acquires the first sound from the user, the line information of the communication terminal 10, and the ticket identification information from the call center 20 via the communication means 23. The acquisition means 31 also acquires the second sound from the ticket holder (hereinafter, the ticket holder is also simply referred to as the "holder") from the venue device 40.

The generating means 32 generates first biometric information of the user based on a first sound acquired from the user when the user requests the purchase of a product. Specifically, the generating means 32 generates first voiceprint information based on the user's voice acquired from the call center 20 via the acquiring means 31. The first voiceprint information indicates the characteristics of the voice of the user who purchased the ticket. A known method is used for generating voiceprint information based on voice. In addition, the first biometric information does not have to be called voiceprint information, but may be information indicating the characteristics of the user's voice (e.g., frequency, etc.).

Furthermore, when the first sound is a reverberation sound from the user in response to a voice from the communication terminal 21, the generating means 32 may generate identification information of the user's ear as the first biometric information. The reverberation sound from the user is a sound that reverberates in the user's ear, and therefore has characteristics that depend on the shape of the user's ear. The generating means 32 extracts the characteristics that depend on the shape of the user's ear from the reverberation sound, and generates the first biometric information.

The generating means 32 also generates second biometric information of the holder based on a second sound acquired from the holder of the product. Specifically, the generating means 32 generates second voiceprint information based on the voice of the holder acquired from the venue device 40. The second voiceprint information indicates characteristics of the voice of the ticket holder. The generating means 32 may also generate ear identification information of the holder as the second biometric information from the echo of the holder in response to the sound output from the venue device 40.

The association means 33 stores the first biometric information and the line information of the communication terminal 10 in association with the ticket identification information.

The function of generating the first biometric information and the function of generating the second biometric information may each be realized by a different component. In this case, the component having the function of generating the first generated information is referred to as a first generating means. Also, the component having the function of generating the second generated information is referred to as a second generating means.

The determination means 34 compares the first biometric information and the second biometric information to determine whether the first biometric information and the second biometric information are obtained from the same person. In this way, the determination means 34 determines whether the holder of the ticket is the same person as the user who purchased the ticket. For example, when the first biometric information and the second biometric information match and when the difference between the first biometric information and the second biometric information is within a predetermined range, the determination means 34 determines that the holder of the ticket is the same person as the user who purchased the ticket. On the other hand, for example, when the first biometric information and the second biometric information do not match and when the difference between the first biometric information and the second biometric information exceeds a predetermined range, the determination means 34 determines that the holder of the ticket is not the same person as the user who purchased the ticket.

In addition, when the judgment means 34 judges that the holder is not the user based on the first biometric information and the second biometric information, the judgment means 34 judges whether the holder is the user based on the line information of the communication terminal 10. Specifically, when the judgment means 34 makes a judgment based on the line information, the server 30 transmits an authentication number to the communication terminal 10 using the line information of the communication terminal 10 acquired by the acquisition means 31. For example, the server 30 transmits the authentication number to the communication terminal 10 by SMS (Short Message Service) using a telephone number. When the number input by the ticket holder to the venue device 40 matches the above-mentioned authentication number, the judgment means 34 detects that the authentication number has been received by the holder's communication terminal. In this case, the judgment means 34 judges that the ticket holder is the same person as the user who purchased the ticket. On the other hand, when the number input by the ticket holder to the venue device 40 does not match the above-mentioned authentication number, the judgment means 34 judges that the ticket holder is not the same person as the user who purchased the ticket.

When the judgment means 34 determines that the ticket holder is the same person as the user who purchased the ticket, the instruction means 35 transmits an instruction to the venue device 40 to allow the purchaser to enter. In addition, when the judgment means 34 does not determine that the ticket holder is the same person as the user who purchased the ticket, the instruction means 35 transmits an instruction to the venue device 40 to restrict the purchaser's entry. Upon receiving an instruction to restrict the purchaser's entry, the venue device 40 notifies, for example, the ticket holder and venue staff that the holder's entry will be restricted.

The venue device 40 comprises a sound collection means 41, a reading means 42, a notification means 43 and a communication means 44. The venue device 40 is installed, for example, at the entrance of a venue where the ticketed event will be held.

The sound collection means 41 collects a second sound from the ticket holder. The sound collection means 41 is, for example, a microphone. For example, the ticket holder speaks to the sound collection means 41 following instructions from an event staff member. This allows the sound collection means 41 to collect the voice of the ticket holder. The venue device 40 also outputs sound to the ticket holder and collects the reverberation of that sound from the ticket holder as the second sound.

The reading means 42 reads the ticket identification information from the barcode or the like printed on the ticket. The identification information read by the reading means 42 is associated with the second sound from the holder acquired by the sound collection means 41, and is transmitted to the server 30 by the communication means 44 described below.

The notification means 43 notifies the ticket holder or event staff of the content transmitted from the instruction means 35. The notification means 43 is a display or a speaker.

The configuration of the judgment system 1 has been described above. Next, an example of the operation of the judgment system 1 will be described with reference to FIG. 2. It is assumed that at the start of the operation example of the judgment system 1, the user of the communication terminal 10 has spoken to an operator in the call center 20 via the communication terminal 21 and completed the purchase process of a ticket for the event. It is also assumed that the communication means 23 of the call center 20 has transmitted the user's voice used in the call, the line information of the communication terminal 10, and the identification information of the purchased ticket to the server 30. It is also assumed that in this operation example, the first biometric information is first voiceprint information generated from the voice of the user of the communication terminal 10. It is also assumed that the second biometric information is second voiceprint information generated from the voice of the ticket holder.

The acquisition means 31 of the server 30 acquires the user's voice, line information of the communication terminal 10, and ticket identification information from the communication means 23 (S101).

The generating means 32 generates first voiceprint information indicating the voiceprint of the user from the voice of the user acquired by the acquiring means 31 (S102). The user here refers to the purchaser of the ticket.

The association means 33 associates the first voiceprint information and line information with the ticket identification information and stores them (S103).

Next, the acquisition means 31 acquires the voice of the ticket holder and the ticket identification information from the venue device 40 (S104). In this operation example, the sound collection means 41 of the venue device 40 acquires the voice of the ticket holder. The reading means 42 acquires the ticket identification information by reading a barcode or the like printed on the ticket held by the holder. The acquisition means 31 then acquires the voice of the ticket holder and the ticket identification information that are associated with each other via a communication line.

The generation means 32 generates second voiceprint information indicating the voiceprint of the ticket holder from the voice of the ticket holder (S105).

The judgment means 34 judges whether the first voiceprint information and the second voiceprint information belong to the same person (S106). Specifically, as described for the judgment means 34 in the explanation of the configuration of the judgment system 1, the judgment means 34 makes this judgment by comparing the first voiceprint information and the second voiceprint information. In the process of S106, the judgment means 34 compares the first voiceprint information and the second voiceprint information associated with the same ticket identification information.

If the determination means 34 determines that the first voiceprint information and the second voiceprint information belong to the same person (Yes in S106), the instruction means 35 outputs an instruction to permit entry to the notification means 43 via the communication means 44 (S107). In response to the instruction from the instruction means 35, the notification means 43 notifies, for example, the ticket holder and an event staff member that the holder is permitted to enter.

If the determination means 34 determines that the first voiceprint information and the second voiceprint information do not belong to the same person (No in S106), the server 30 transmits authentication information to the communication terminal 10 based on the line information (S108). For example, the server 30 transmits a number of digits as authentication information for a telephone number, which is the line information.

At this time, the venue device 40 accepts input of authentication information from the ticket holder via a display or the like (S109). The venue device 40 transmits the accepted authentication information to the server 30.

The judgment means 34 determines whether the authentication information sent to the communication terminal 10 matches the authentication information received by the venue device 40 (S110).

If the authentication information matches (Yes in S110), the instruction means 35 outputs an instruction to permit entry to the notification means 43 (S111).

If the authentication information does not match (No in S110), the instruction means 35 outputs an instruction to restrict entry to the notification means 43 (S112). In response to the instruction from the instruction means 35, the notification means 43 notifies, for example, the ticket holder and venue staff that entry of the holder will be restricted.

The above describes the operation of the judgment system 1.

As described above, the judgment system 1 includes a generating means 32 and a judging means 34. The generating means 32 generates first biometric information of the user based on a first sound acquired from the user when the user requests the purchase of a product. The generating means 32 also generates second biometric information of the holder of the product based on a second sound acquired from the holder. The judging means 34 judges whether the holder is the user based on the first biometric information and the second biometric information.

In order to prevent resale, a method could be considered that places some kind of restriction on the owner of a product when the purchaser of the product and the owner of the product are different people. To use this method, it is necessary to determine whether the purchaser of the product and the owner of the product are the same person. However, in the technology shown in Patent Document 1, after performing the process of sending a request to purchase the product, it is necessary to perform a separate process of registering biometric information, which makes the process for the purchaser of the product cumbersome.

On the other hand, in the determination system 1, the first biometric information of the user who is the purchaser of the product is generated based on the first sound acquired from the user when the user requests the purchase of the product. As a result, in the determination system 1, the user performs the process of purchasing the product and does not need to register his/her own biometric information separately from the purchasing process. In this way, the determination system 1 can simplify the process for the user while suppressing resale.

In the determination system 1, the generation means 32 generates a first biometric information based on a first sound from the user acquired from the user's communication terminal 10. Furthermore, when the determination means 34 determines that the holder is not the user based on the first biometric information and the second biometric information, it determines whether the holder is the user based on the line information of the communication terminal 10.

In the judgment system 1, the judgment means 34 judges whether the holder is a user based not only on the biometric information but also on the line information of the communication terminal 10. As a result, even if the judgment means 34 makes an incorrect judgment, for example, because the first biometric information is affected by noise contained in the first sound from the communication terminal 10, it is possible to accurately judge whether the holder is the same person as the user who purchased the product by making a judgment based on the line information. Furthermore, the line information of the communication terminal 10 is the one used when purchasing the product. Therefore, the user does not need to perform a process just to register the line information.

In addition, in the judgment system 1, the judgment means 34 transmits authentication information to the user's communication terminal when it judges that the holder is not the user based on the first biometric information and the second biometric information. Furthermore, when the judgment means 34 detects that the authentication information has been received by the holder's communication terminal, it judges that the holder is the user.

With this configuration, the determination means 34 determines whether the holder is a user who has purchased the product based on the fact that the holder's communication terminal has received the authentication information. This makes it possible to more accurately determine whether the holder is a user than when, for example, a staff member at an event venue visually checks the line information.

In addition, in the judgment system 1, the instruction means 35 instructs the holder to be permitted to enter the event venue when it is determined that the holder is a user. In addition, the instruction means 35 instructs the holder to be restricted from entering the event venue when it is determined that the holder is not a user.

By being equipped with the instruction means 35 as described above, the judgment system 1 can instruct the ticket holder or event staff on how to respond to the holder.

The above describes the judgment system 1.

<Modification>
A description will be given of a determination system 1A which is a modified example of the first embodiment. The determination system 1A has a similar configuration to the determination system 1 shown in Fig. 1. The determination system 1A operates according to the flowchart shown in Fig. 3.

In the above-mentioned determination system 1, when the determination means 34 determines that the holder is not a user based on the first biometric information and the second biometric information, it determines whether the holder is a user based on the line information of the communication terminal 10. The determination system 1A is a form that does not make a determination based on the line information.

Each component of judgment system 1A is similar to the components of judgment system 1, so it will be omitted.

The operation of the judgment system 1A will be explained with reference to Fig. 3. It is assumed that at the start of the operation example of the judgment system 1A, the user of the communication terminal 10 has spoken to an operator in the call center 20 via the communication terminal 21 and completed the purchase process of a ticket for the event. It is also assumed that the communication means 23 of the call center 20 has transmitted the user's voice used in the call and the identification information of the purchased ticket to the server 30.

The acquisition means 31 of the server 30 acquires the user's voice and ticket identification information from the communication means 23 (S101A).

The generation means 32 generates first voiceprint information indicating the user's voiceprint from the user's voice acquired by the acquisition means 31 (S102A).

The association means 33 associates the first voiceprint information with the ticket identification information and stores it (S103A).

Next, the acquisition means 31 acquires the ticket holder's voice and ticket identification information from the venue device 40 (S104A).

The generation means 32 generates second voiceprint information indicating the voiceprint of the ticket holder from the voice of the ticket holder (S105A).

The determination means 34 compares the first voiceprint information with the second voiceprint information to determine whether the first voiceprint information and the second voiceprint information belong to the same person (S106A). In the process of S106A, the determination means 34 compares the first voiceprint information and the second voiceprint information associated with the same ticket identification information.

If the judgment means 34 determines that the first voiceprint information and the second voiceprint information belong to the same person (Yes in S106A), the instruction means 35 outputs an instruction to permit entry to the notification means 43 via the communication means 44 (S107A).

If the determination means 34 determines that the first voiceprint information and the second voiceprint information do not belong to the same person (No in S106), the instruction means 35 outputs an instruction to restrict entry to the notification means 43 (S112A). In response to the instruction from the instruction means 35, the notification means 43 notifies, for example, the ticket holder and staff at the event venue that entry of the ticket holder will be restricted.

The above describes the operation of judgment system 1A.

As described above, the judgment system 1A, like the judgment system 1, includes a generation means 32 and a judgment means 34. Therefore, like the judgment system 1, the judgment system 1A can simplify the processing for the user while suppressing resale.

Second Embodiment
The determination system 2 in the second embodiment will be described with reference to Fig. 4 and Fig. 5. As shown in Fig. 4, the determination system 2 includes a first generating unit 51, a second generating unit 52, and a determining unit 53.

The first generating means 51 generates first biometric information of the user based on the first sound acquired when the user requests to purchase a product. The first generating means 51 is realized, for example, by the generating means 32 in the determination system 1.

The second generating means 52 generates second biometric information of the holder of the product based on the second sound acquired from the holder. The second generating means 52 is realized, for example, by the generating means 32 in the determination system 1.

The judgment means 53 judges whether the holder is a user based on the first biometric information and the second biometric information. The judgment means 53 is realized, for example, by the judgment means 34 in the judgment system 1.

Next, the operation of the determination system 2 will be described with reference to Figure 5. In this operation example, a voiceprint generated from a voice is used as the first biometric information and the second biometric information.

The first generation means 51 generates first biometric information of the user based on the user's voice used when requesting the purchase of a product (S201).

The second generation means 52 generates second biometric information of the holder of the product based on the voice of the holder (S202).

The judgment means 53 judges whether the holder is a user based on the first biometric information and the second biometric information (S203).

As described above, the judgment system 2 comprises a first generating means 51, a second generating means 52, and a judgment means 53. The first generating means 51 generates first biometric information of the user based on a first sound acquired from the user when the user requests the purchase of a product. Furthermore, the second generating means 52 generates second biometric information of the holder of the product based on a second sound acquired from the holder. The judgment means 53 judges whether the holder is the user based on the first biometric information and the second biometric information.

In order to prevent resale, a method could be considered that places some kind of restriction on the owner of a product when the purchaser of the product and the owner of the product are different people. To use this method, it is necessary to determine whether the purchaser of the product and the owner of the product are the same person. However, in the technology shown in Patent Document 1, after performing the process of sending a request to purchase the product, it is necessary to perform a separate process of registering biometric information, which makes the process for the purchaser of the product cumbersome.

On the other hand, in the determination system 2, the first biometric information of the user who is the purchaser of the product is generated based on the first sound acquired from the user when the user requests the purchase of the product. As a result, in the determination system 2, the user performs the process of purchasing the product and does not need to register his/her own biometric information separately from the purchasing process. In this way, the determination system 2 can simplify the process for the user while suppressing resale.

Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above-mentioned embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
